1. What is household electricity supply?
Ans. Household electricity supply refers to the electrical energy that is supplied to residential buildings for the purpose of powering various appliances and devices used within the household. It is the electricity that is distributed by power companies to individual homes through electrical wiring systems.
2. How is household electricity supplied?
Ans. Household electricity is supplied through a network of power lines that connect the residential buildings to the main electrical grid. The electricity generated at power plants is transmitted at high voltages through these power lines and then stepped down to lower voltages by transformers before reaching individual homes. It is then distributed within the house through electrical wiring and outlets.
3. What are the components of a household electricity supply system?
Ans. The components of a household electricity supply system include the main electrical grid, power lines, transformers, electrical meters, service cables, circuit breakers, electrical wiring, and outlets. The main electrical grid is responsible for generating and transmitting electricity, while the transformers, meters, cables, and circuit breakers facilitate the distribution and measurement of electricity within the house.
4. How is household electricity usage measured?
Ans. Household electricity usage is measured using an electrical meter, which is installed near the main electrical panel of the house. The meter records the amount of electricity consumed by the household in kilowatt-hours (kWh). It allows homeowners to monitor their energy consumption and enables power companies to bill customers accurately based on their electricity usage.
5. Are there any safety precautions to consider with household electricity supply?
Ans. Yes, there are several safety precautions to consider with household electricity supply. It is important to have proper grounding and insulation in electrical wiring to prevent electrical shocks. Regular maintenance and inspection of electrical systems, such as circuit breakers and outlets, are crucial to ensure their safe operation. It is also important to avoid overloading circuits and to use electrical appliances and devices as per their recommended electrical load capacities.
